Atmospheric, Sea Ice, & Oceanic Properties in the Southern Ocean
Atmospheric, Sea Ice, & Oceanic Properties in the Southern Ocean
Science Behind the ImageIn the past 20 years, climate science and computational modeling have been thrust into the national spotlight as climate change has become a pressing global issue. The Sixth Assessment Report by the Intergovernmental Panel on Climate Change (released in August 2021) makes extensive use of climate models to predict the effects of future emissions scenarios. One of those models, the Energy Exascale Earth System Model (E3SM), is featured in this visualization project.
The earth's climate is complex with many interacting processes. Climate models mirror this complexity but allow researchers to analyze each variable at high resolution in space and time. Evaluation of these large data sets is important for climate science for verification, scientific understanding, and assessment of future emissions scenarios. The E3SM model was developed by researchers at the U.S. Department of Energy. The data in this visualization was generated on Argonne National Laboratory supercomputers by Mark Petersen of the Los Alamos National Laboratory.
Visualization Behind the ImageThis visualization and its accompanying video demonstrates the use of the E3SM model to study the impact of polynyas. Polynyas are openings within the polar sea ice pack formed and sustained by atmospheric and oceanic processes. They occur in the Arctic and Southern oceans, last for many months, and function as a conduit for heat and water between the oceanic and atmospheric systems. In this image we see the extent of the Antarctic ice on a particular day in the Antarctic winter with a large polynya in the Weddell Sea. The ocean surface shows latent heat flux — the transfer of heat between the ocean and the atmosphere. Pathlines show surface winds over the 10-day period prior to the timestep. The visualization was created by Francesca Samsel and Greg Abram using the Stampede2 supercomputer at TACC using Paraview and custom code visualization tools.

Top View of Storm Anvil Showing Breaking Wave & Trailing Cirrus Plume
Science Behind the ImageA feature called an Above Anvil Cirrus Plume (AACP) has been observed in supercell thunderstorms by aircraft and satellite data and has been the subject of numerical study. The AACP is observed as an elongated elevated "tier" of ice cloud that extends downwind from the overshooting top. This feature is important to atmospheric researchers and forecasters because three-fourths of all supercells exhibiting AACP's were associated with severe weather (large hail and/or damaging winds/tornadoes). Understanding the specific conditions by which AACP's form in supercells is therefore of great interest as they have the potential to serve as a useful "nowcasting" device during severe weather events. Simulation credit: Leigh Orf from the University of Wisconsin, Madison. Completed on TACC's Frontera supercomputer.
Visualization Behind the ImageThis visualization used a combination of 3D techniques to visualize the top of the storm. The volume visualization provided a view of the cloud ice which revealed the presence of the AACP. Animations of the cloud like rendering revealed the mechanism of formation of the plume to be a wave like structure similar to that seen in a hydraulic jump. Paraview with OspRAY ray tracing was used to produce the visualization.

Desalination Membranes to Maximize Flow, Clean More Water
Desalination Membranes to Maximize Flow, Clean More Water
Science Behind the ImageThis 3D model of a polymer desalination membrane shows water—the silver channels moving from top to bottom—avoiding dense spots in the membrane and slowing flow.
Researchers from Iowa State, Penn State, and UT Austin found that creating a uniform membrane density down to the nanoscale of billionths of a meter is crucial for maximizing the performance of reverse-osmosis, water-filtration membranes. Their discovery was published online by the journal Science and was the cover paper of the Jan. 1, 2021, print edition.
Working with Penn State's transmission electron microscope measurements of four different polymer membranes used for water desalination, the Iowa State engineers used TACC supercomputers to predict water flow through 3D models of the membranes, allowing detailed comparative analysis of why some membranes performed better than others.
The researchers concluded that the key to better desalination membranes is figuring out how to measure and control at very small scales the densities of manufactured membranes. Manufacturing engineers and materials scientists need to make the density uniform throughout the membrane, promoting water flow without sacrificing salt removal.
Visualization Behind the ImageThe Science cover image was created by Greg Foss, a visualization expert and artist at TACC, in collaboration with the Iowa State researchers. Foss also contributed to the manuscript illustrations. This visualization was generated using ParaView (Kitware, Inc.) and OSPRay (Intel, Inc.) without additional post-processing. This visualization realizes the promise of high-fidelity visualization: putting "cover quality" rendering in the tools used for immediate analysis, providing a single environment for exploratory analysis through final production render (i.e. no need to post-process in Maya, Blender, etc). The image was created running on TACC's Frontera and Stampede2 HPC systems.

Atomically-Thin Layer of Hexagonal Boron Nitride
Atomically-Thin Layer of Hexagonal Boron Nitride
Science Behind the ImageA single atomically-thin layer of hexagonal boron nitride shows that thinner is better with regards to radio-frequency switching applications.
Hexagonal boron nitride (hBN) has a large bandgap, high phonon energies, and an atomically smooth surface absent of dangling bonds. As a result, it has been widely used as a dielectric to investigate electron physics in two-dimensional heterostructures and as a dielectric in the fabrication of two-dimensional transistors and optoelectronic devices.
Here we show that hBN can be used to create analogue switches for applications in communication systems across radio, 5G, and terahertz frequencies. Our approach relies on the non-volatile resistive switching capabilities of atomically thin hBN. The switches are composed of monolayer hBN sandwiched between two gold electrodes and exhibit a cutoff-frequency figure of merit of around 129 THz with a low insertion loss (≤0.5 dB) and high isolation (≥10 dB) from 0.1 to 200 GHz, as well as a high power handling (around 20 dBm) and nanosecond switching speeds, metrics that are superior to those of existing solid-state switches. Furthermore, the switches are 50 times more efficient than other non-volatile switches in terms of a d.c. energy-consumption metric, which is an important consideration for ubiquitous mobile systems. We also illustrate the potential of the hBN switches in a communication system with an 8.5 Gbit s–1 data transmission rate at 100 GHz with a low bit error rate under 10−10.

Volume Rendering of a Cosmological Simulation of the Universe
Volume Rendering of a Cosmological Simulation of the Universe
Science Behind the ImageThis is an image from a cosmological simulation of the Universe performed by the Enzo multi-physics hydrodynamics code. Enzo is used to study the physical processes present in the evolution of the cosmos. To learn more, read "Ray Tracing the Cosmos" by Texascale.
Visualization Behind the ImageThe visualization was performed using a modified version of the yt open source data analysis and visualization package. The yt-project grew out of the Enzo community to satisfy a need to visualize and analyze the large data resulting from the Enzo simulations. Collaborators at TACC and the National Center for Supercomputing Applications (NCSA) modified the yt framework to utilize a ray tracing back end called GraviT to perform volume rendering of the adaptive mesh refinement data. This image shows a volume rendering of density in which the color and opacity are mapped to the density distribution.
The visualization was performed by Dave Semeraro of TACC and Matthew Turk of NCSA.
Aggregate and Monomers in Saturated Aqueous Solution
Aggregate and Monomers in Saturated Aqueous Solution
Science Behind the ImageNumerous membrane-less organelles (i.e. dense, liquid-like droplets) exist in eukaryotic cells and they afford spatial and temporal modes of cellular regulation through the functional organization or assembly of DNA, RNA, and protein constituents. Pathological changes in the properties of these liquid-like droplets towards more static, fibrous aggregates are thought to underlie the progression of neurodegenerative diseases. A fundamental understanding of the biophysical mechanisms that drive 'normal', or non-pathological, phase separation is a critical first step towards understanding how they are altered in disease states. We have been particularly interested in the physicochemical properties of the protein backbone (i.e. the chemical scaffold common to all proteins) and the role these properties play in protein-mediated phase separation. Molecular dynamics simulations of a model protein backbone system in a super-saturated solution allows us to probe or investigate these properties at atomic resolution. The accompanying figure is a snapshot from such a simulation performed on Stampede2 and captures the approach of free polypeptides as they phase separate from solution to form liquid-like droplets.
Visualization Behind the ImageThe image scene was staged using VMD and rendered using the Tachyon Ray Tracer with ambient light occlusion. A semi-transparent surface representation encapsulates the liquid-like droplet and the individual protein backbone model components can be seen within as van Der Waals spheres colored by atom types.

Arctic Ocean research - Ice interactions
Arctic Ocean research - Ice interactions
Science Behind the ImageThe image shows a daily average temperature field from a numerical model simulation of warm sub-surface water of subtropical origin carried with the Norwegian Atlantic boundary current into the Arctic Ocean, northwestward along the West Spitsbergen current and northeastward through Barents Sea opening. The view is northeastward, from Iceland toward the Fram Strait and the eastern Arctic, with Svalbard at the center, Greenland to the left, and Eurasia to the upper right. The horizontal extent covers 1320 x 1080 grid points, which corresponds to physical dimensions of ~5000 km x 3500 km. 33 vertical levels comprise the depth range between 0-1400 m. Temperature ranges from 0 (blue) to 6ºC (red). High performance computing is required to capture mesoscale eddies of length-scale less than 15 km shedding off and transporting heat and freshwater toward the ocean interior. Understanding how these currents transport heat into the high Arctic and its surrounding seas will enable the quantification of the impact of recent observed changes in the atmosphere and ocean heat content on Arctic sea ice and ecosystems, as well as Greenland's marine margins. Supported by NSF grants PLR-1603903 and PLR-1708289, and through continuing support from NASA for the "Estimating the Circulation and Climate of the Ocean (ECCO) project.

Molecular Dynamics Analysis of Ion Distributions Around a DNA strand
Molecular Dynamics Analysis of Ion Distributions Around a DNA strand
Science Behind the ImageThe charged ions that surround DNA molecules can dramatically effect its conformation, folding, and dynamics. This visualization is from a Molecular Dynamics simulation of a DNA system where the electron density of the surrounding ions was critical to understanding how they might modulate the structure and interactions of the DNA double helix.
Visualization Behind the ImageThis visualization was produced as part of an ECSS (https://www.xsede.org/for-users/ecss) collaboration where TACC HPC researcher Antonio Gomez assisted Daniel Roe to significantly optimize the parallelization and parallel IO of the trajectory analysis CCPTRAJ subroutine of the Molecular Dynamics package AMBER. AMBER is one of the most widely used Molecular Dynamics packages at TACC, and this optimization effort reduced the time for analyses that required the CCPTRAJ subroutine from days to minutes. The image is a single snapshot from a 20000 time-step trajectory output from AMBER on stampede, and was rendered using the VMD Tachyon renderer.

Physical Signatures of Cancer Metastasis
Physical Signatures of Cancer Metastasis
Science Behind the ImageMetastasis is the development of secondary malignant growths at a distance from a primary site of cancer. In order to study physical signatures of metastasis, Abdul Malmi Kakkada, Xin Li, Himadri Samanta (post-docs in Dave Thirumalai's group - Department of Chemistry at the UT Austin) and Sumit Sinha (Graduate Student in Thirumalai group) have established a model for the proliferation behavior of tumor cells.This model is used to provide detailed analyses of individual cell trajectories and identify complex spatial/time dependent cell migration patterns. This provides insights into how cells are "prepared" for invasion into areas surrounding the tumor. The visualization shown depicts the velocity of each cell (colored by the magnitude of the velocity with the arrows representing the direction). In the tumor cross-section, it is clear to see that faster moving cells are concentrated at the outer periphery of the tumor. Arrows indicating the velocity direction show that cells in the periphery tend to move farther away from the center of the tumor as opposed to cells closer to the center of the tumor whose direction of motion is essentially isotropic. This prediction agrees well with the experiments, which showed that cells at the periphery of the tumor spheroid move persistently along the radial direction, resulting in polarized tumor growth.
Visualization Behind the ImageThe models and simulations are done in MATLAB on the Stampede supercomputer at the Texas Advanced Computing Center. Most of the simulations require 1 node and 2 days of compute time to complete. In order to improve the visual fidelity of the 3D cell propagation data, the simulation data was visualized in Paraview 5.3 using the OSPRay renderer by Anne Bowen at the Texas Advanced Computing Center.

Liquid K–Na Alloy Anode Enables Dendrite‐Free Potassium Batteries
Liquid K–Na Alloy Anode Enables Dendrite‐Free Potassium Batteries
Science Behind the ImageSchematic of making solid‐metal anodes into liquid‐alloy anode to suppress dendrite formation. Dendrites form on Na or K solid surface on charge and grow across the separator to the cathode to give an internal short‐circuit. In contrast, the mixing of Na and K results in a room‐temperature K–Na liquid alloy which allows a dendrite‐free large‐capacity battery. The immiscibility of the liquid K–Na in liquid organic electrolytes offers the possibility of a liquid–liquid anode–electrolyte interface. The three layers top‐to‐bottom represent cathode, electrolyte, and anode.

Electronic tattoo
Electronic tattoo
Science Behind the ImageTattoo-like epidermal sensors are an emerging class of truly wearable electronics, owing to their thinness and softness. While most of them are based on thin metal films, a silicon membrane, or nanoparticle-based printable inks, we report submicrometer thick, multimodal electronic tattoo sensors that are made of graphene. The graphene electronic tattoo (GET) is designed as filamentary serpentines and fabricated by a cost- and time-effective "wet transfer, dry patterning" method. It has a total thickness of 463 ± 30 nm, an optical transparency of ∼85%, and a stretchability of more than 40%. The GET can be directly laminated on human skin just like a temporary tattoo and can fully conform to the microscopic morphology of the surface of skin via just van der Waals forces.
Visualization Behind the ImageConceptual image created using Autodesk Maya and Adobe Illustrator and Photoshop to show how the sensor pattern is separated from the substrate after printing, as well as the flexibility of the tattoo.

Streamwise Vorticity in a Supercell Thunderstorm
Streamwise Vorticity in a Supercell Thunderstorm
Science Behind the ImageThis wild-looking image compares variables from the dataset of a simulated hypothetical thunderstorm that spawned a tornado. The plot shows vortex lines, the gold streamlines modeled from vorticity, compared with wind velocity as grey streamlines with red representing highest speed values. The scene illustrates rotation in the updraft, the hallmark characteristic of a supercell. Featured is a vortex ring at the top of the storm, which forms as the strong updraft punches into the stable stratosphere and the air subsequently curls downward. A translucent volume rendering of cloud water combined with ice provides reference to the surrounding storm structure. In a real storm, you can see the clouds billowing upward and corkscrew striations in the rotating cloud, but the relationship between the wind and rotation isn't exactly clear. Plots like this help to illuminate this relationship giving a better sense of how the vorticity in the environment is tilted, stretched, and intensified in the updraft to make the storm rotate. The image illustrates how vorticity in the environment aligns with the winds feeding into the storm to enhance storm rotation.
Visualization Behind the ImageThe visualization illustrates a structure in the dataset that the researcher wasn't aware of — the vortex ring. The meteorologist plans to incorporate this image in an upcoming seminar, and TACC will use the image in venues to promote the NSF XSEDE initiative, HPC, and visualization resources. The visualization was created with VisIt software (Lawrence Livermore National Lab) on Longhorn at the Texas Advanced Computing Center. The simulation was run on Kraken (National Institute for Computational Sciences). More specifically, TACC staff had to translate the netcdf data from the simulation into hdf to incorporate the irregular spaced Z coordinates that the user provided. The 1500x1500x50 grid is regular in x & y and the dataset includes several variables including wind velocity, reflectivity, perturbated potential temperature, cloud water mixing ratio, ice, vorticity, and others. TACC staff built several animations and stills.

Graphene and Electronics and Thermal Management
Graphene and Electronics and Thermal Management
Science Behind the ImageWhen graphene is placed on an amorphous substrate like SiO2, thermal conductivity of graphene is strongly suppressed. In this work, the researchers measured how thermal conductivity depends on the number of graphene layers stacked on top of each other. They developed a theoretical model, and found that phonons in graphene hit the graphene-SiO2 interface, and interaction of phonons with interface is the major reason for thickness-dependent thermal conductivity of graphene samples. The result is relevant for the application of graphene for electronics, thermal management, and other applications

Spinning Star
Spinning Star
Science Behind the ImageSolar and stellar observations reveal diverse and vibrant manifestations of magnetic activity, including the dramatic eruptions known as flares and coronal mass ejections. Yet, elucidating the origins of solar and stellar magnetism is a formidable task, requiring an understanding of the subtle nonlinear interplay between turbulent convection and rotation on a vast range of spatial and temporal scales.
Visualization Behind the ImageFacing this complexity requires sophisticated modeling and visualization on high-performance computing platforms. These images were made from a simulation of a rapidly spinning star with mass similar to our sun. The images show a cross section through the turbulent convection zone where rapid rotation distorts the convection patterns, forming elongated flow structures that play an essential role in the generation of the magnetic field. Such structures exhibit intense vorticity, swirling columns of plasma that wrap up and amplify magnetic fields. These 3D views allow scientists to identify and characterize the type of structures that may exist in turbulent stellar interiors, which are important to investigating energy transport. TACC staff built the animation with VisIt on Longhorn and the Ranger supercomputer as a computation resource. Several variables were modeled and combined in different ways over the course of the project to end up with: 1) velocity, 2) radial component of velocity modeled as a scalar colored with enstrophy; and 3) the radial component velocity colored by negative and positive values showing upwelling and downwelling. Users Ben Brown (University of Wisconsin at Madison) and Mark Miesch (University Corporation for Atmospheric Research) are investigating energy transfer.

Breaking Waves
Breaking Waves
Science Behind the ImageThe simulation of complex free-surface phenomena such as breaking waves, spray sheets, and air entrainment play a key role in the design and operation of naval combatants. As a ship progresses through water, steep breaking waves are formed; spray is shed along the crests of the breaking waves and near the ship's bow where thin sheets of water form. Air is also entrained along the turbulent face of breaking waves and along the contact line where the free surface, which is the interface between the air and water, intersects the hull. These phenomena are among the most challenging problems in computational fluid dynamics today. The image shows the resulting turbulence as water flows past a NACA 0024.
Visualization Behind the ImageThe visualization was created using a Virtual Rheoscopic Fluid plot. The plot uses the fluid velocity data to create and orient virtual rheoscopic particles to obtain an image similar to those used in bench experiments. This technique enables novel vector plots in VisIt on a wide variety of data and the visual comparison of the quality of different technique variations.

Drug Delivery Systems to Aid Heart Disease
Drug Delivery Systems to Aid Heart Disease
Science Behind the ImageThe vast majority of heart attacks occur when there is a sudden rupture of vulnerable plaques forming clots that cause blockages in coronary arteries. The diseased arteries can be treated with drugs intravascularly injected into these rupture-prone plaques. In designing the local drug delivery devices, important issues regarding drug distribution and targeting need to be addressed to ensure therapeutic efficacy. In this case, a computational toolset was developed to support the design and analysis of a catheter-based local drug delivery system that uses nanoparticles as drug carriers to treat vulnerable plaques and diffuse atherosclerosis. Simulations were run on a 3D patient-specific diseased coronary artery segment obtained directly from CT-imaging data. The visualization depicts a cross-section of the artery taken right through the vulnerable plaque with a large lipid core and a thin fibrous cap that is formed near the coronary artery bifurcation region. Results show the drug (in red) accumulating in the lipid core of the vulnerable plaque, which is highly encouraging from a therapeutic point of view.

Global Seismic Wave Propagation
Global Seismic Wave Propagation
Science Behind the ImageModeling propagation of seismic waves through the Earth helps assess seismic hazard at regional scales and aids in interpretation of the Earth's inter structure at global scales. In this simulation of global wave propagation from the 2011 Tohoku earthquake, the Earth is modeled using hexahedral elements that are adaptively sized based on the local length of seismic waves. A discontinuous Galerkin method is used for the numerical solution of the seismic wage propagation partial differential equations.
Visualization Behind the ImageThe simulation was run on the TACC Lonestar IV system and produced ~3.4 terabytes of data for 330 time steps. The visualization was run on 32 nodes and 64 GPUs of the TACC Longhorn system.

Science Behind the ImageProject Summary: No high-level project summary provided.
Visualization Behind the ImageTACC staff enhanced NVIDIA's CUDA Isosurfacer to perform twice as fast by using one-third of the GPU memory, and enabling efficient overlapping of GPU operations with I/O operations and sort-last image compositing to achieve high throughput, in-core rendering. The enhanced isosurfacer achieves an approximate speedup for 4.5x over CPU-based visualization methods on a 2048^3 scalar volume. The images show enstrophy data, isosurfaced using the modified NVIDIA CUDA isosurfacer. It was created using 64 nodes of Longhorn. It took 2.5 minutes to isosurface 935M triangles, 68G cells, which correspond to 256 GB of data. Additionally, it took 9 seconds to render the images on 128 GPUs. The two frames show the assignment of data to process by color.

Ozone Concentration in East Texas Due to Emissions in Houston
Ozone Concentration in East Texas Due to Emissions in Houston
Science Behind the ImageThis visualization shows simulations of ozone concentrations in eastern Texas. Emissions in Houston cause ozone concentrations to rise in other parts of the state, particularly in central and north Texas; thus, it is apparent that emissions from one city can affect ozone levels in an entire region. These simulations use various sources of data including satellite observations and land-based measurements.
Visualization Behind the ImageTACC staff developed a custom OpenGL application to visualize the data sets. This application combines geospatial data with the simulations to produce time-series animations of the ozone concentration across Texas. Cutting planes and isosurfaces show the ozone concentration in units of parts-per-billion.

Visualization of NARA Record Collections
Visualization of NARA Record Collections
Science Behind the ImageThe National Archives and Records Administration (NARA) is responsible for ensuring continuous access to government records. To preserve and provide access to electronic records collections, archivists need to first conduct a series of analysis to discover their structure and content and to make decisions about long-term preservation needs. TACC's research examines information visualization for archival analysis and long-term preservation planning of terabyte size collections.
Visualization Behind the ImageThis type of visualization work is intended to help digital archivists at NARA process their Federal Electronic Records collection for public access and long-term preservation. In response, TACC developed a program for NARA that visualized a test-bed collection of approximately 40,000 files. The visualization was rendered by a visual analytic application developed in Java. The application leveraged several existing information visualization packages, including Prefuse, JFreeChart, and OpenCloud. It includes publicly available data provided by Federal Agencies or harvested from their websites. Each record group corresponds to all the records of a small Federal Agency or some of the records of a larger Federal Agency and is represented as a node that includes child nodes. In turn, each record group may have different types of digital objects bearing different arrangements and a variety of file formats. The sample from the test-bed collection contained 1,031,118 files in 200 different formats with up to 12 levels of hierarchical nesting. Each square represents a directory within the file system with larger squares containing a higher number of files. The colors in the first image (casc_filetype) indicate the types and percentage of file formats present in those directories: green = web files; blue = images; coral = pdf files; light blue = video files; and red = word processing files. This view infers that this test-bed collection contains a majority of web pages including photographs. The color black indicates that there are file formats that current software could not identify.
The second picture (casc_datamining) presents the results of a data mining analysis showing that the files are organized by similar naming conventions (light green); in sequential order (orange); by date (brown); or by geographical location (bordeaux).

Building Affinity for Effective Drugs
Building Affinity for Effective Drugs
Science Behind the ImageIncreasing the strength of binding between a molecule and a receptor is an important technique in the design of effective drugs. Binding affinity synthesizes molecules that are already in the shape that they will take when bound to a receptor. This technique works because it decreases the binding entropy, which increases the overall binding affinity. The research addresses biological and medical challenges from single molecules to the genome with high-performance computing and theory. In collaboration with other experimental groups, the researchers use computer modeling and simulations to understand these complex biomolecular systems and to discover molecules for treating disease and improving human health. Image Caption 1: Frame from the molecular dynamics (MD) simulation of constrained and unconstrained molecule bound to receptor. These calculations revealed that the origin of the constrained molecule (purple) and unconstrained molecule (pink) have similar conformations when bound to the receptor. Image Caption 2: Frame from the molecular dynamics (MD) simulation of the constrained and unconstrained molecule free in solution. In solution, the unconstrained molecule (pink) is capable of forming more compact structures that allow hydrogen bonds (green dotted line) to be formed with the phosphate group (represented by the yellow and red atoms).
Visualization Behind the ImageYue Shi of the The Ren lab at The University of Texas at Austin probed the origin of this entropy paradox with molecular dynamics simulations run on the Lonestar and Ranger supercomputers at TACC. TACC staff used VMD to load the molecular dynamics data and to set up the model and the Tachyon Parallel Ray Tracer to render it. Their group used approximately 2 million CPU hours on Ranger and about 1 million CPU hours on Lonestar.

Cosmic Web
Cosmic Web
Science Behind the ImageScience is entering the era of precision cosmology, where it is becoming possible to measure cosmological parameters with less than 1% error. Large numerical simulations are used to model the main physical processes to establish a 'standard ruler' with which to measure universal phenomena. The mysterious Dark Energy component of the Universe is of particular interest, as it accounts for more than 70% of known energy density ― it is responsible for causing cosmic expansion to accelerate, and yet its nature is still completely unknown.
Visualization Behind the ImageThe visualization was completed in VisIt using both point plots and direct volume ray casting to show the particle field and particle density. This visualization shows particle density from a 3072^3 (29 billion particle) N‐body simulation of dark matter in a computational volume of (1/h Gpc)^3 (100 billion cubic light years) on a computational grid of 6144^3 cells and force softening length of 16/h kpc (74 thousand light years), evolved to the present epoch (z=0).

BP Deepwater Horizon Oil Spill
BP Deepwater Horizon Oil Spill
Science Behind the ImageThe animation depicts wind velocity, water levels, inundation, and passive particle movement obtained from a simulation of past hurricanes computed using the ADCIRC coastal circulation model coupled to the unstructured SWAN wave model. The initial particle distributions vary from simulation to simulation. Some points are hypothetical; others reflect the position of the oil on the surface and vary in date from 06/20/2010 to 06/23/2010 to 06/27/2010. Positions were derived from the NOAA/NESDIS Experimental Marine Pollution Surveillance Daily Composite Product (http://www.ssd.noaa.gov/PS/MPS/deepwater.html). Particles in the animation move with the depth-averaged water velocity and most accurately represent water movement in shallow estuarine, near shore, and continental shelf waters that were strongly mixed during the storm. Particle motion beyond the continental shelf is not reliable. During the simulation, particles do not disburse, stick, or degrade in any way. They may not accurately represent the movement of oil. These results should not be used to forecast the movement of material at the sea surface or in the water column during any future event.
Visualization Behind the ImageThe visualization effort by TACC focused on the overlay of particle movement and satellite or aerial imaging data. The particles in the visualization representing the oil spill and their position is either hypothetical or reflects the position of the oil on the surface. The data was visualized using TACC's Longhorn visualization system and MINERVA, an open source geospatial software. The data was generated daily and is approximately 100 GB in size.

While most people probably don't use a secure connection to reach Bing, those who do are being warned by their browsers this morning that something may be amiss. A misconfigured X.509 certificate on Microsoft's Bing search engine sites is causing errors for visitors over HTTP Secure (HTTPS) connections.
The certificate, which was apparently misconfigured by Akamai (which front-ends Bing for Microsoft), threw up warnings on browsers—including Internet Explorer—that the site might be fraudulent. A Firefox error indicated that the certificate was configured to be "only valid for the following names: a248.e.akamai.net , *.akamaihd.net , *.akamaihd-staging.net."
As of 10:30am Eastern time, the problem was still blocking visits to Bing via HTTPS. One poster on Hacker News who spotted the error on Chrome commented, "At first I thought it was a joke from Google. Something like: 'No you don't want to use bing, here is Google.'"
But the certificate problem isn't just restricted to Bing. Other Akamai customers, including NBA.com, are also affected by the malformed certificates.

At UN, Obama welcomes signs of Iranian moderation
UNITED NATIONS (AP) — President Barack Obama on Tuesday welcomed the new Iranian government's pursuit of a 'more moderate course,' saying it should offer the basis for a breakthrough on Iran's nuclear impasse with the United Nations and the US...
UNITED NATIONS (AP) — President Barack Obama on Tuesday welcomed the new Iranian government's pursuit of a "more moderate course," saying it should offer the basis for a breakthrough on Iran's nuclear impasse with the United Nations and the U.S. He signaled a willingness to directly engage Iran's leaders, tasking Secretary of State John Kerry with pursuing that diplomacy with Tehran.
"The roadblocks may prove to be too great, but I firmly believe the diplomatic path must be tested," Obama said during an address to the U.N. General Assembly.
Obama issued a stern message to the international body itself, saying its ability to meet the test of the times is being challenged by the dispute over what to do about Syria's chemical weapons. He called on the U.N. Security Council to pass a resolution that would enforce consequences on Syrian President Bashar Assad if he fails to follow a U.S.-Russian deal to turn his chemical weapon stockpiles over to the international community.
The president also addressed criticism of his shifting strategy for responding to an August chemical weapons attack in Syria. The U.S. seemed on the brink of a military strike before Obama abruptly decided to seek congressional approval, then joined the Russians in pursuing a diplomatic resolution.
"The situation in Syria mirrors a contradiction that has persisted in the region for decades: The United States is chastised for meddling in the region and accused of having a hand in all manner of conspiracy," he said. "At the same time, the United States is blamed for failing to do enough to solve the region's problems, and for showing indifference toward suffering Muslim populations."
Obama announced that the United States would provide $339 million in additional humanitarian aid to refugees and countries affected by the Syrian civil war, bringing the total U.S. aid devoted to that crisis to nearly $1.4 billion.
As the General Assembly meetings opened, the situation in Syria was overshadowed by a flurry of friendly gestures between the U.S. and Iran's new government. Obama said recent statements by Iranian President Hasan Rouhani, a moderate cleric elected in June, should offer the basis for a meaningful agreement on Iran's disputed nuclear program.
The West has long suspected that Iran is seeking a nuclear weapon. Tehran has consistently denied the charge.
Obama, reflecting the skepticism of many in the U.S. and around the world, said Rouhani's "conciliatory words will have to be matched by actions that are transparent and verifiable."
Obama said he was asking Kerry to pursue diplomatic progress with Iran, in coordination with five other world powers. Kerry will join representatives from those nations Thursday in a meeting with Iranian Foreign Minister Mohammad Javad Zarif.
It's unclear whether Kerry and Zarif will meet one-on-one on the sidelines of that meeting. And Obama also offered no hints of whether he will meet Tuesday with Rouhani. Even a brief handshake would be significant, marking the first such encounter between U.S. and Iranian leaders in 36 years.
Zarif joined the Iranian delegation in the hall for Obama's address. In Iran, the main domestic TV channels did not run speech live.
Obama arrived at the annual U.N. meetings with diplomatic opportunities, not only on Iran and Syria but also on the elusive effort to seal lasting peace between the Israelis and Palestinians. While the prospects of a peace accord remain as slim as ever, the two sides have resumed direct talks, partly as a result of months of lobbying by Kerry.
The president praised Israeli and Palestinian leaders for their willingness to take "significant political risks" in order to get back to the negotiating table.
"Now the rest of us must also be willing to take risks," he said, adding that the United States must recognize that Israel's security depends on the formation of a Palestinian state.
Obama will meet later Tuesday with Palestinian Authority President Mahmoud Abbas. He'll also hold talks at the White House next week with Israeli Prime Minister Benjamin Netanyahu.
Israel is watching closely as the U.S. and Iran edge close to direct negotiations. The previous Iranian president, Mahmoud Ahmadinejad, repeatedly threatened the destruction of Israel, and Israeli leaders have pushed Obama to be more forceful with the threat of military action in response to Tehran's pursuit of a nuclear weapon.
While Obama has said all options are on the table when it comes to dealing with Iran, he has preferred to use economic sanctions as a prod. The sanctions have had a substantial effect on Iran, leading to a spike in inflation and unemployment.
American officials say the Iranian public's frustration with a deteriorating economy led to Rouhani's election and is driving his change in tone. But it is still unclear whether Iran is willing to take the steps the U.S. is seeking in order to ease the sanctions, including curbing uranium enrichment and shutting down the Fordo underground nuclear facility.
Congressional officials from both parties have urged Obama to maintain tough sanctions until Iran makes significant nuclear concessions. Top Democratic and Republican senators sent Obama separate letters this week that also urged him to make clear to Tehran's new leadership that the U.S. will not accept a nuclear-capable Iran.
Obama also addressed the continued turmoil in the Arab world, where pro-democracy movements have had mixed results over the past two years. He defended the White House's decision to maintain ties with the interim government in Egypt, which took over after the military ousted the country's first democratically elected leader.
However, he said future American support "will depend on Egypt's progress in pursuing a democratic path."
The U.S. provides Egypt with about $1.5 billion a year, mostly military aid. The president's top national security aides have recommended suspending much of the money.

The family of Trayvon Martin called President Barack Obama's comments in which he said the slain Florida teen could have once been him "a beautiful tribute to our boy."
Getty Images
In a statement Friday, Tracy Martin and Sybrina Fulton said they were honored by the president's remarks, his first public comments addressing George Zimmerman's acquittal:
"We are deeply honored and moved that President Obama took the time to speak publicly and at length about our son, Trayvon. The President's comments give us great strength at this time. We are thankful for President Obama's and Michelle's prayers, and we ask for your prayers as well as we continue to move forward.
We know that the death of our son Trayvon, the trial and the not guilty verdict have been deeply painful and difficult for many people. We know our family has become a conduit for people to talk about race in America and to try and talk about the difficult issues that we need to bring into the light in order to become a better people.
What touches people is that our son, Trayvon Benjamin Martin, could have been their son. President Obama sees himself in Trayvon and identifies with him. This is a beautiful tribute to our boy.
Trayvon's life was cut short, but we hope that his legacy will make our communities a better place for generations to come. We applaud the President's call to action to bring communities together to encourage an open and difficult dialogue. Our family is committed to this dialogue through the work of the Trayvon Martin Foundation.
We seek a future when a child can walk down the street and not worry that others see him as dangerous because of the color of his skin or the clothes on his back. We seek a future where our children can grow up and become the people God intended them to be."

Michael Ealy
Life Path Number 4
Michael Ealy is an American actor, best known for his roles as Ricky Nash in Barbershop (2002), Slap Jack in 2 Fast 2 Furious (2003), Jake Attica in Takers (2010), Danny in About Last Night (2014), and Carter Duncan in The Perfect Guy (2015).
He was born on Friday August 3rd 1973, in Washington, District of Columbia, United States.
Michael Ealy is practical, down to earth with strong ideas about right and wrong. He is orderly and organized, systematic and controlled. Decisive and methodical Michael is employing a step by step rational approach to problems solving, and once committed - he does not give up easily!
Ealy is not one for "get rich quick" schemes. Seeking to establish a solid foundation, Michael Ealy would rather use hard work and long hours to build a business or career. Precise, tenacious and persevering, he has great potential for success, but only after putting out effort and overcoming the limitations he so often encounters. Justice and honesty are sacred to Michael. He is reliable and dependable, a cornerstone in the community.
Though not an idealist, Michael Ealy is willing to work for a better world in a realistic way. However, he can be rigid in his ideas and sometimes too quick in judging his fellow man. He is loyal to those he loves and works well with others. It is important that while being part of a team Ealy has his own responsibility and well-defined task; he performs better when his responsibilities are not overlapping with those of others. Michael Ealy has to be careful not to be bossy and rude. He possesses rare discipline and perseverance and not everyone can keep up with him.
Michael can handle money carefully and likes the security of a nest egg.
Ealy's love of work often leads him into a career early in life. Because of his methodical nature Michael can easily become rigid and stuck in convention. He can also be overly cautious when changes are necessary, this can cause him to miss opportunities that present themselves. Michael Ealy must cultivate flexibility in his character. He is well suited for marriage and often becomes a responsible loving parent. However, anything that violates Michael's profound sense of order, such as separation or divorce can be a shattering experience for him. Michael Ealy easily becomes obsessed and even vengeful, seeking his own definition of justice.
Michael is courageous and a true survivor. He is a builder and the foundation of any enterprise. His hard work and practical, traditional values pay off to provide Michael Ealy with the rewards he seeks and deserves.
You and Michael
About Michael's Life Path number

Modi from India goes to the doctor and says, "I feel terrible."
Doctor says, "go home, gang raipe your womenfolk, put on a suicide belt and walk around the neighborhood threatening people, sell some illegal drugs to high school students in the local convenience store, then burn some young brides by sprinkling kerosene on them and lighting them up. Do all of the above for three days."
Week later Modi goes back and says, "Doc, I feel wonderful, what was the problem?"
Doctor, "you were homesick!"
That about articulates the hindu/hindoo culture in India!
You are full of caca..

The city sealed its reputation as India's "raipe capital" two years ago when a medical student died after being gang-raiped on a moving bus. The figures were released the same day that an Uber taxi driver accused of raiping a female passenger in Delhi last month
